“…The entrance design is also challenging as it should allow fish to enter the gear without letting it swim back to escape, such as demonstrated by Tran et al (2020) with crustacean pots. Then, two types of entrances (triangular-shaped versus rectangularshaped) were compared (C4; Figure 2).…”

The French fishing industry is becoming increasingly environmentally aware and likely to adopt more sustainable fishing gears. As a result, fishers are showing a growing interest in sustainable fish pots. This experiment aimed to develop a fish pot concept specifically based on target species behavior in French coastal waters. First, the consultation led with fishers indicated the black seabream as the main species of interest. Then, the pot’s characteristics were defined to comply with fishing regulations. The conception process of the pot was led step-by-step by gradually testing a pot design appropriated to black seabream’s natural behavior. The approach and feeding behaviors of black seabream were described using underwater video combined to an ethogram. The experiment led to a prototype of fish pot, which provide fishers with an innovative fishing gear.

“…The female crab (Portunus pelagicus) with dark gray eggs is found in the depth range of 0.35 to 31.0 m, the substrate is sandy to muddy, and the presence of different levels of embryo development indicates a wide distribution habitat from shallow water to deep water [4] . Meanwhile, natural mortality and catch are factors that will reduce the amount of stock [22] , as well as the use of fishing gear that can affect ecosystem fertility [29] , even research on environmental factors in general additive models in Taiwanese waters., stated that the concentration of chlorophyll-a (Chl-a) and demersal temperature affected the catch rate of the crab (Portunus pelagicus) [32] . However, changes in environmental conditions in Western Australian waters affect two determinants of CPUE, including fishing power (q) and abundance (N) [17] , a similar study with an ecosystem component approach based on participatory multicriteria analysis (MCDA).)…”

This study presents an overview of the condition of the crab (Portunus pelagicus) resources in the waters of Bangkalan Madura, as an export commodity its production relies on the catch, one of the locations of the catchment area is in the Fisheries Management Area 712 where this research was carried out. The frequency of fishing efforts continues to increase because of the high economic value, however, there is not much information about the condition of the resources. Descriptive research method with the aim of mapping crab resources based on the "Non-Equilibrium Walter-Hilbron Model". The results showed that the maximum catch production (CMSY) was 63,886.114 kg/year with standard Trammel net fishing gear, the intrinsic growth was 50.91%/year, the carrying capacity of the waters was 50195,336 Kg/year, the dominant species was (Portunus pelagicus), the optimal effort (Eopt) was 6363750 trips/year with a potential resource of 25097,668 kg/year. In conclusion, this research can be used as a basis for resource mapping as a follow-up to Minister of Marine Affairs and Fisheries Regulations Number 70/2016 concerning the Management Plan for Crab in the WPP.
